Make small and beautiful HE-AAC music in Linux (using NeroAACCodec)

In the Linux production of small and beautiful HE-AAC format music (using NeroAACCodec) -- Linux general technology-Linux technology and application information, the following is the details of reading. Apart from the MP3 format, the most common ISO standard music format should be none of AAC! In addition to the Apple iPod, there are not a few music mobile phones on the market that support AAC. In addition, AAC is several times better than MP3 in terms of compression capabilities, it allows music to maintain a better quality in a relatively low file size. So it is of course the first choice to put it on a mobile phone or Walkman ??

In Linux, the most common and common AAC encoder is FAAC! FAAC is a set of free software, so FAAC is of course the most accepted in Linux, but among the many AAC encoding specifications, FAAC supports Main and LC (Low Complexity) LTP (Long Term Predicition) and LTP (Long Term Predicition) are not doing well in the case of low metarate. Therefore, the encoding method described in this article is HE (High Efficiency), also known as AAC +, it is the most suitable for encoding Low Bit Rate specifications.

Among the many encoders, Nero AAC Codec is a few encoder supporting encoding HE-AAC, but fortunately Nero AAC Codec has developed a version for Linux, although not free software, however, for personal purposes, the order is free of charge.

Name: Nero AAC Codec
Type: Music Transfer
Authorization: Free Software
Official Website: Ahead Nero Software AG
Download: [Download Page]

After downloading Nero AAC Codec, open the terminal window and move it to the directory where the downloaded file is located, and then unlock it:

$ Unzip./NeroDigitalAudio.zip

After unlocking, there will be two more folders and some files. In "linux", we have installed the encoder (neroAacEnc) and Decoder (neroAacDec ), please grant these two files the execution permission and use Root to copy the two files to/usr/local/bin for future operations.

$ Chmod + x neroAacDec neroAacEnc
$ Sudo cp./neroAacDec/usr/local/bin
$ Sudo cp./neroAacEnc/usr/local/bin

Then we can use Nero AAC Codec to make MPEG4 HE-AAC file ?? The performance of this HE-AAC file in 48 kbps is basically the same as the 128 kbps of MP3, so basically I am converting to 48 kbps, this saves a lot of space on your mobile phone or Walkman!

$ NeroAacEnc-he-br 48000-if infile.wav-of outfile. m4a

In addition, the bit rate unit of this program is bps, that is to say, if you want to specify 48 kbps, it should be converted to 48000. In addition, although Nero AAC Codec supports HEv2, is there a problem? The result of self-turning is quite bad, so we can use HE.

If you really hate the text mode, you can also use soundKonverter to make some modifications. Although it is set to faac by default, we only need to change the Advanced Options slightly:

　　

(400) {this. resized = true; this. width = 400; this. alt = 'click here to open new window';} "onmouseover =" if (this. resized) this. style. cursor = 'hand'; "onclick =" window. open ('HTTP: // farm4.static.flickr.com/3158/2427670188_cabf848dc7_o.png'); ">

Although this method is not a good one, it should be a good method for patients who are heavily dependent on the GUI.
